Summary
🤩
Rockstar🎓
Top SchoolNaoto Usuyama is a Principal Researcher at Microsoft Research in Seattle with 14 years of experience building AI systems for precision health, pharmacy, and applied computer vision. He leads work on multimodal foundation models for radiology and pathology (including projects like GigaPath, BiomedParse, LLaVA-Med and BioViL) and develops biomedical LLMs such as Medprompt GPT-4 and domain-specific BERT variants. His research has produced practical, high-impact outputs—e.g., fast medication identification published in Nature Digital Medicine and the ePillID low-shot pill identification benchmark presented at CVPR. Prior roles span applied research and software engineering at Microsoft and Microsoft Japan, where he contributed to widely used mobile imaging apps like Office Lens. He is also an active ML engineer in open source, implementing PyTorch U-Net and ResNet-based segmentation models that reflect hands-on expertise in medical image analysis. Combining deep research, product-minded engineering, and open-source practice, he focuses on translating multimodal AI into clinically useful tools.
